How do stacks and queues compare in terms of performance?

Stacks and queues are both abstract data types, but they have different performance characteristics based on their operations. Stacks use LIFO (Last In, First Out) while queues use FIFO (First In, First Out). This affects their performance in various scenarios.

What are the time complexities for common operations?

For stacks, push and pop operations are O(1). For queues, enqueue and dequeue operations are also O(1). However, the performance can vary based on the underlying data structure used.

Can you give examples of when to use each?

Certainly! Use stacks for scenarios like backtracking algorithms or undo mechanisms. Use queues for scheduling tasks or handling requests in order.

Are there any real-world applications for these data structures?

Yes, stacks are used in function call management in programming languages, while queues are used in print job management and task scheduling in operating systems.
